How to Choose an Industrial Multirotor Platform

Overview

• Start from the sensor, not the airframe — gimbal mass and power draw set the payload floor.
• For close inspection of insulators, fittings and fasteners, hover accuracy matters more than top speed.
• Endurance is only comparable at the same payload and wind condition; ask for the condition, not just the figure.
• Confirm the payload interface is documented. An undocumented mount turns a product purchase into a custom project.

Start from the mission, not from the spec sheet

The most common way to get a multirotor selection wrong is to start with a payload number and work backwards. A 15 kg figure tells you what the aircraft can lift, not what it can do for a full sortie in your wind, at your altitude, with the sensor you actually need. Start instead with what the aircraft has to achieve in one flight, and treat payload as one of several budgets that have to close at the same time.

Three budgets usually decide the outcome: mass, power and time. Mass is the payload plus its mount. Power is what the payload draws on top of the flight controller, the link and any onboard compute. Time is how long the aircraft has to stay on station at the required image quality. A configuration that satisfies two of the three is not a configuration — it is a problem that shows up on site.

What to decide before comparing models

Write down the mission in one sentence, then the constraint that would break it. For inspection work the constraint is usually image quality at a stand-off distance; for delivery it is mass over a fixed route; for night work it is sensor choice and lighting. Once the breaking constraint is named, the shortlist narrows quickly — and the reason for the shortlist can be explained to whoever signs the purchase.

Then decide the operating envelope: temperature range, typical and gust wind, precipitation, and the altitude band. These set the floor. An airframe that is marginal in your worst month will be marginal every month, because the days you most need to fly are rarely the calm ones.

Sizing payload without fooling yourself

Treat the payload as a system, not a weight. A gimbal is mass plus power draw plus a data path plus a mounting envelope. Two payloads with the same mass can have very different consequences: one may need a regulated 12 V rail with inrush headroom, the other may run fine on 5 V. The limiting factor is usually the power budget or the centre-of-gravity range, not the kilogram number.

Where several payloads must run together, confirm it per configuration rather than assuming the mounting points imply it. See multi-payload platform configuration for how we assess combinations, and M-30 for a platform built around that use.

What we need from you to answer properly

A useful first enquiry states the mission objective and what counts as success, the coverage (area, distance per sortie, altitude band), the payload with its power draw, the environment, what data has to come out and where it must go, the jurisdiction and approvals, and quantity with timing. That is the same list we ask for on the contact page.

If some of it is unknown, say so and mark it uncertain. An honest gap is far easier to work with than a confident guess, and it is the difference between a configuration we can stand behind and one we cannot.
